The dielectric signature of glass density

At present, we are witnessing a renewed interest in the properties of densified glasses prepared by isobaric cooling of a liquid at elevated pressure. As high-pressure densification emerges as a promising approach in the development of glasses with customized features, understanding and controlling their unique properties represent a contemporary scientific and technological goal. The results Read more about The dielectric signature of glass density[…]

Ultrastable glasses portray similar behaviour to ordinary glasses at high pressure

Vapour deposited ultrastable glasses have gained much attention since its discovery in 2007 by the group of Mark Ediger. By physical vapour deposition, at proper deposition conditions, it is possible to obtain, in just few minutes, glasses with a thermodynamic stability that rivals the stability of glasses naturally aged for millions of years, i.e. ambers.
